Naked man on bridge sidewalk was stabbed, beaten

An off-duty lifeguard saw the victim in Normal Heights and performed CPR

San Diego  San Diego police are trying to determine the identity of a man found on a Normal Heights bridge overpass Thursday night who was stabbed and apparently beaten.

The man, who was unclothed and had multiple bruises, may have been dropped off on the Adams Avenue bridge over Interstate 805, police Lt. Paul Rorrison told reporters.

An off-duty lifeguard saw the victim about 10:30 p.m. and performed CPR.

The man, believed to be in his 20s, was on the sidewalk and had suffered stab wounds to the chest and broken ribs, police Officer David Stafford said. He was transported to Scripps Mercy Hospital, where he was being treated for life-threatening injuries.

Police had both ends of the bridge blocked off with yellow crime-scene tape as they investigated.
